Fungicidal effect of 4-HBA, Folicur and their mixture toward F. culmorum and A. alternata at day 10 of in vitro testing.

Fungi	Diameter of control colonies, mm	Substances and concentrations, ppm
		4-HBA, 200		Folicur, 0.5		4-HBA, 200 + Folicur, 0.5
		Colony diameter, mm	Growth inhibition, %	Colony diameter, mm	Growth inhibition, %	Colony diameter, mm	Growth inhibition, %
F. culmorum	90.0 ± 0.0	89.0 ± 0.3	1.1 ± 0.4	60.8 ± 1.1	32.0 ± 0.8	35.8 ± 0.9	61.0 ± 1.8
A. alternata	90.0 ± 0.0	84.0 ± 0.7	6.7 ± 0.8	67.0 ± 0.0	28.0 ± 0.0	32.7 ± 0.0	64.0 ± 0.0

Differences between Folicur and Folicur + 4-HBA treatments are significant at p ≤ 0.002. The differences among all treatments from the control are also significant (p < 0.05).
